1. OPERATING INSTRUCTIONS
WARNING! Ensure that you read, understand and apply the safety instructions and warnings before use.
WARNING! Ensure that you have familiarized yourself thoroughly with the product and the hazards
associated with its improper use.
1.1 Before first use of this product, pour a teaspoon of good quality air tool lubricant into the hose quick coupler-
male, then connect it to air source and turn on the air valve and work for 3 seconds to evenly distribute
lubricant.
1.2 Use the slotted end of the handle to turn the release valve clockwise until it is firmly closed.
1.3 Apply the emergency brake and use wheel chocks to block all wheels to prevent any movement of the
vehicle being lifted.
1.4 Place the jack into position and adjust the extension screw as needed.
NOTE: Check in your vehicle owner's manual for the location of recommended lift point.
1.5 Connect the air quick coupler-male into the shop air supply hose quick coupler-female, then turn on the air
valve.
1.6 Raise the load to desired height, turn off the air valve and immediately USE JACK STANDS with adequate
capacity to support the load.
1.7 When air source is not available, insert the big end of the handle into the handle bracket, pump it manually
to raise the load to desired height. Then immediately transfer the load to appropriate support devices such
as jack stands.
WARNING! Be sure all tools and personnel are clear before lowering load.
1.8 When work is done, raise load enough to carefully remove the jack stands. Then SLOWLY and
CAREFULLY lower the load by turning the release valve counterclockwise (use the slotted end of the
handle) in extremely small increments, then lower the extension screw by turning it clockwise as needed
and remove the jack.
WARNING! Dangerous dynamic shock loads are created by quick opening and closing the release valve
when the load is being lowered. The resulting overload may cause hydraulic system failure
which could cause severe personal injury and/or property damage.
2. MAINTENANCE
2.1 Clean the outside of the jack with dry, clean and soft cloth and periodically lubricate the joints, extension
screw and all moving parts with a light oil as needed. DO NOT APPLY LUBRICANT TO SADDLE.
2.2 When not in use, store the jack in a dry location with ram and extension screw fully lowered.
2.3 Purge the hydraulic system to eliminate any air in the system if jack efficiency drops or jack doesn’t work:
A. If manual operation performs poorly, use the slotted end of the handle to turn the release valve 1-1/2 turns
counterclockwise and remove the oil filler plug by gently pulling, insert the handle into the handle bracket and
pump it 10 to 15 times, then replace the filler plug.
B. If air operation performs poorly, connect the air inlet fitting to air source, use the slotted end of the handle to
turn the release valve 1-1/2 turns counterclockwise and remove the oil filler plug by gently pulling, turn on the
air valve to let the pump work for one minute, then replace the filler plug.
2.4 Check the hydraulic oil: place the jack in an upright position, completely lower the ram and remove the filler
plug, if it is not adequate, fill with high quality hydraulic jack oil to the lower rim of the fill hole, purge away air
from the hydraulic system as described in 2.3, top off with more hydraulic oil, then replace the filler plug.

2.5 For best performance and longest life, replace the complete jack oil at least once per year: With the ram
fully lowered, remove the oil filler plug, lay the jack on its side and drain the oil into a suitable container, then
fill with high quality hydraulic jack oil as described in 2.4, reinstall the filler plug.
NOTE: Dispose of hydraulic oil in accordance with local regulations.
2.6 It is recommended that an annual inspection be done by qualified technicians.
